A substance from a fungus that infects caterpillars could offer new treatment hope for sufferers of osteoarthritis according to new research.
Cordycepin is an active compound isolated from the caterpillar fungus Cordyceps militaris and has proved to be effective in treating osteoarthritis by blocking inflammation in a new way, through reducing a process called polyadenylation. The research was undertaken by scientists from the University of Nottingham and supported by funding from Versus Arthritis. The findings have been published today in Scientific Reports.
Dr. Cornelia De Moor from the University of Nottingham’s School of Pharmacy led the study and said: “The natural compound cordycepin is derived from a caterpillar fungus which is famous in the Far East for its medicinal properties. In this paper we show that orally administrated cordycepin reduces pain and halts disease progression in animal models of osteoarthritis. Intriguingly, it does this by a different mechanism than any other known anti-inflammatory painkiller, through affecting the last step of making a messenger RNA, polyadenylation. This means that medicines derived from cordycepin may help patients for whom other treatments have failed. We hope that cordycepin will prove to be the founder of a new class of pain killer, the polyadenylation inhibitors. There is a long way to go before a cordycepin derived medicine reaches patients, but our work is very promising we are very excited about the prospects.”
